Researchers from Rensselaer Polytechnic Institute have spent several years researching ways to harness plants’ natural abilities to filter toxins out of the air into an application that could be used in indoor spaces like office buildings. Those researchers have now unveiled the first public-scale prototype of their green wall.

IAQ monitoring and management systems can provide a healthy and productive indoor environment while saving both energy and money, notes Navigant Research. Worldwide revenue from IAQ systems is forecast to grow from $3.3 billion in 2014 to nearly $5.6 billion by 2020.

It’s time again for the Commercial Cooling Showcase. The NEWS’ annual issue has traditionally introduced the latest air conditioning units available for the upcoming summer season. The intent is to help contractors prepare for this busy period by doing the research that will help them distinguish between brands.

Ultra-Sun Technologies, a research and manufacturing company in Corona, Calif., has been acquired by Field Controls LLC, further expanding the company’s IAQ capabilities. Ultra-Sun is a leading developer of IAQ products to clean and purify the air in homes, offices, clean rooms, and commercial buildings.
